I just updated the software on my E61 RM89 and the language reverted back to Chinese. I used nemesis to change the language code from 0538687 to 0534841 but The Nokia Software updater says there is no update available since my new release is 3.0633.09.04.

Is there a way I can roll the phone back to an earlier release and do the upgrade? Is there another way to recover from this situation?
